Answer:
The correct answer will be "". The further explanation is given below.
Explanation:
The potential energy will be,
⇒
The expression of force will be,
⇒
⇒
⇒
Force seems to be appealing because the expression has been negative. It therefore means that the force or substance is acting laterally in on itself.
Answer:
The pressure after passing the valve is 23,8 [Kpa] ( 0,234 atm) and the pressure drop is about 1,53 [Kpa]
Explanation:
We need to use the formula of bernoulli, in the attached image we can see the fluid throw the pipe, we also can calculate the velocity inside the pipe using the flow rate and the cross sectional area.
For this case, we don't use the elevation difference and therefore those terms can be cancelled.
When the area has reduced the velocity of the fluid is increased but there is a drop pressure through the valve.
